* `ActiveRecord::Base#becomes` should copy the errorsVokhmin Alexey V2015-12-141-0/+12

* Use a bind param for `LIMIT` and `OFFSET`Sean Griffin2015-12-141-0/+5
| | | | | | | | | | | | | | | We currently generate an unbounded number of prepared statements when `limit` or `offset` are called with a dynamic argument. This changes `LIMIT` and `OFFSET` to use bind params, eliminating the problem. `Type::Value#hash` needed to be implemented, as it turns out we busted the query cache if the type object used wasn't exactly the same object. This drops support for passing an `Arel::Nodes::SqlLiteral` to `limit`. Doing this relied on AR internals, and was never officially supported usage. Fixes #22250.

| * Conditionally convert the raw_value received by the numeric validator.Roque Pinel2015-07-111-12/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes the issue where you may be comparing (using a numeric validator such as `greater_than`) numbers of a specific Numeric type such as `BigDecimal`. Previous behavior took the numeric value to be validated and unconditionally converted to Float. For example, due to floating point precision, this can cause issues when comparing a Float to a BigDecimal. Consider the following: ``` validates :sub_total, numericality: { greater_than: BigDecimal('97.18') } ``` If the `:sub_total` value BigDecimal.new('97.18') was validated against the above, the following would be valid since `:sub_total` is converted to a Float regardless of its original type. The result therefore becomes Kernel.Float(97.18) > BigDecimal.new('97.18') The above illustrated behavior is corrected with this patch by conditionally converting the value to validate to float. Use the post-type-cast version of the attribute to validate numericality [Roque Pinel & Trevor Wistaff]
* | All strings returned by `ImmutableString` should be frozenSean Griffin2015-10-152-11/+7
| | | | | | | | | | | | | | I seriously don't even know why we handle booleans, but those strings should technically be frozen. Additionally, we don't need to actually check the class in the mutable string type, since the `cast_value` function will always return a string.
* | Add an immutable string type to opt out of string dupingSean Griffin2015-10-153-20/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This type adds an escape hatch to apps for which string duping causes unacceptable memory growth. The reason we are duping them is in order to detect mutation, which was a feature added to 4.2 in #15674. The string type was modified to support this behavior in #15788. Memory growth is really only a concern for string types, as it's the only mutable type where the act of coersion does not create a new object regardless (as we're usually returning an object of a different class). I do feel strongly that if we are going to support detecting mutation, we should do it universally for any type which is mutable. While it is less common and ideomatic to mutate strings than arrays or hashes, there shouldn't be rules or gotchas to understanding our behavior. However, I also appreciate that for apps which are using a lot of string columns, this would increase the number of allocations by a large factor. To ensure that we keep our contract, if you'd like to opt out of mutation detection on strings, you'll also be option out of mutation of those strings. I'm not completely married to the thought that strings coming out of this actually need to be frozen -- and I think the name is correct either way, as the purpose of this is to provide a string type which does not detect mutation. In the new implementation, I'm only overriding `cast_value`. I did not port over the duping in `serialize`. I cannot think of a reason we'd need to dup the string there, and the tests pass without it. Unfortunately that line was introduced at a time where I was not nearly as good about writing my commit messages, so I have no context as to why I added it. Thanks past Sean. You are a jerk.

* | `validates_acceptance_of` shouldn't require a database connectionSean Griffin2015-09-251-4/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | The implementation of `attribute_method?` on Active Record requires establishing a database connection and querying the schema. As a general rule, we don't want to require database connections for any class macro, as the class should be able to be loaded without a database (e.g. for things like compiling assets). Instead of eagerly defining these methods, we do it lazily the first time they are accessed via `method_missing`. This should not cause any performance hits, as it will only hit `method_missing` once for the entire class.
* | Improve the performance of `save` and friendsSean Griffin2015-09-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The biggest source of the performance regression in these methods occurred because dirty tracking required eagerly materializing and type casting the assigned values. In the previous commits, I've changed dirty tracking to perform the comparisons lazily. However, all of this is moot when calling `save`, since `changes_applied` will be called, which just ends up eagerly materializing everything, anyway. With the new mutation tracker, it's easy to just compare the previous two hashes in the same lazy fashion. We will not have aliasing issues with this setup, which is proven by the fact that we're able to detect nested mutation. Before: User.create! 2.007k (± 7.1%) i/s - 10.098k After: User.create! 2.557k (± 3.5%) i/s - 12.789k Fixes #19859
* | Clean up the implementation of AR::DirtySean Griffin2015-09-242-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | This moves a bit more of the logic required for dirty checking into the attribute objects. I had hoped to remove the `with_value_from_database` stuff, but unfortunately just calling `dup` on the attribute objects isn't enough, since the values might contain deeply nested data structures. I think this can be cleaned up further. This makes most dirty checking become lazy, and reduces the number of object allocations and amount of CPU time when assigning a value. This opens the door (but doesn't quite finish) to improving the performance of writes to a place comparable to 4.1

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Timestamp column can have less precision than ruby timestamp In result in how big a fraction of a second can be stored in the database. m = Model.create! m.created_at.usec == m.reload.created_at.usec # => false # due to different seconds precision in Time.now and database column If the precision is low enough, (mysql default is 0, so it is always low enough by default) the value changes when model is reloaded from the database. This patch fixes that issue ensuring that any timestamp assigned as an attribute is converted to column precision under the attribute.

* | Require dependencies from stdlib in the Decimal typeSean Griffin2015-09-211-0/+2
| | | | | | | | | | | | | | In Active Record, it appears these were either autoloaded, which actually was likely due to test ordering since the method `Float#to_d` wouldn't trigger it. This makes it explicit, and unlikely to fail in the future.
* | Remove no-op options being passed in AM type registrationsSean Griffin2015-09-211-11/+11
| | | | | | | | | | | | The `override` option is only a thing for Active Record registrations. We should figure out how to make this properly error out without doing anything too weird to the code.
* | Move the appropriate type tests to the Active Model suiteSean Griffin2015-09-211-2/+8
| | | | | | | | | | | | | | | | | | Any tests for a type which is not overridden by Active Record, and does not test the specifics of the attributes API interacting in more complex ways have no reason to be in the Active Record suite. Doing this revealed that the implementation of the date and time types in AM was actually completely broken, and incapable of returning any value other than `nil`.
* | Simplify the implementation of Active Model's type registrySean Griffin2015-09-211-97/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Things like decorations, overrides, and priorities only matter for Active Record, so the Active Model registry can be implemented much more simply. At this point, I wonder if having Active Record's registry inherit from Active Model's is even worth the trouble? The Active Model class was also missing test cases, which have been backfilled. This removes the error when two types are registered with the same name, but given that Active Model is meant to be significantly more generic, I do not think this is an issue for now. If we want, we can raise an error at the point that someone tries to register it.
* | Various stylistic nitpicksSean Griffin2015-09-211-4/+3
| | | | | | | | | | | | | | We do not need to require each file from AM individually, the type module does that for us. Even if the classes are extremely small right now, I'd rather keep any custom classes needed by AR in their own files, as they can easily have more complex changes in the future.

After going through the output and adding `.freeze` I was able to eliminate the creation of 1,114 string objects on EVERY request to [codetriage](codetriage.com). How does this impact execution? To look at memory: ```ruby require 'get_process_mem' mem = GetProcessMem.new GC.start GC.disable 1_114.times { " " } before = mem.mb after = mem.mb GC.enable puts "Diff: #{after - before} mb" ``` Creating 1,114 string objects results in `Diff: 0.03125 mb` of RAM allocated on every request. Or 1mb every 32 requests. To look at raw speed: ```ruby require 'benchmark/ips' number_of_objects_reduced = 1_114 Benchmark.ips do |x| x.report("freeze") { number_of_objects_reduced.times { " ".freeze } } x.report("no-freeze") { number_of_objects_reduced.times { " " } } end ``` We get the results ``` Calculating ------------------------------------- freeze 1.428k i/100ms no-freeze 609.000 i/100ms ------------------------------------------------- freeze 14.363k (± 8.5%) i/s - 71.400k no-freeze 6.084k (± 8.1%) i/s - 30.450k ``` Now we can do some maths: ```ruby ips = 6_226k # iterations / 1 second call_time_before = 1.0 / ips # seconds per iteration ips = 15_254 # iterations / 1 second call_time_after = 1.0 / ips # seconds per iteration diff = call_time_before - call_time_after number_of_objects_reduced * diff * 100 # => 0.4530373333993266 miliseconds saved per request ``` So we're shaving off 1 second of execution time for every 220 requests. Is this going to be an insane speed boost to any Rails app: nope. Should we merge it: yep. p.s. If you know of a method call that doesn't modify a string input such as [String#gsub](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37) please [give me a pull request to the appropriate file](https://github.com/schneems/let_it_go/blob/b0e2da69f0cca87ab581022baa43291cdf48638c/lib/let_it_go/core_ext/string.rb#L37), or open an issue in LetItGo so we can track and freeze more strings.
